X-48B BWB Prototype to Fly in 2006

Boeing and NASA will flight test the X-48B, a 21 foot wingspan, 8.5% scale blended wing body (BWB), in 2006 at the Dryden Flight Research Center

The vehicle will be remote-controlled and powered by three turbojets. Boeing is developing the BWB in co-operation with the US Air Force Research
Laboratory who sees it as a possible multi-role military aircraft.

Its always nice to see new shapes in the sky, hopefully this will lead to a full sized aeroplane and also give Airbus a kick up the
arse as their own BWB seems to have been forgotten in all the A380 hoo ha.

The BWB was being plotted in the Boeing gearheads for some time now, but definitely got lost in the rush about the A380 (Which in my opinion will get
beaten out by the 777 and the 787 anyway).

There's only one problem with this otherwise beautiful plane.

Remember the problem with the 747 when it was going to airports? The guys had to widen the airstrips and runways to accomodate the monster wingspan.
This thing looks even wider. How's it supposed to fit on a runway like that?

I also have to question the air force using it as a multirole. It is incredibly similar to the B-2 Bomber in shape. However, the B-2 was made for the
role of bomber, and excels in it. But this one is being made for a civilian purpose. Now I wouldn't be surprised if it went into military duty as a
bomber and such, like they militarized the KC-135 Stratotankers from... whatever they were before. DC-9's, 737's I think, 727's, I dunno. Something
around that.

But yeah, I am happy that Boeing is making a (well, somewhat of a) competitor to the A380. But I stand by my opinion that the 787's and 777's are
the way to go.

EDIT: Also, one more thing. How the heck is this thing supposed to fit into those itty-bitty gates at the airports? Folding wings, maybe, but thats
where the passengers can sit, ain't it?

The picture the Intelgurl posted is a good one, because it shows (by color) where the passengers will sit. So no, they dont sit in the wings.
I'm not sure about what their dimensions will be...if it ever goes commercial.
I believe any airport that can handle a 747, will also be able to handle the BWB.

heres it super imposed over the 747.

Most of the renderings and wind tunnel tests i've seen have 3 engines on the back...but some have had 2 or 4 engines, and a few rare(r) ones actually
have the engines under the little stubby wings...which I'm sure wont be where they would be placed.

If you think about it though the airports are making modifcations for the A380s so im sure that if this plane isn't "too much" different that not
to much taxi way work or gate reconstruction would have to take place.

Somewhere in the afterlife Jack Northrop has little tears of joy in his eyes. This was his original vision for the commercial flying wing design.

I agree Jack would indeed be happy to see this. Atleast he did find out about the B-2 before he died.

This design still has some of the same problems Jack faced such as not many window seats for passengers. Thats not really a big problem IMHO but some
people have issues with that. I think Jack toyed with windows in the roof and even the front in his designs.

I guess now you could even make video panel windows that showed a picture of the outside even though there is no window really there just a camera.

This design has many advantages over conventional commercial airliners. It can carry a drasticaly greater cargo and passenger capacity per gallon of
fuel, it has tremendous lift cabaility, it is very efficient and then again, its also much more stealthy for military. This is a very good design, one
of the best ever put into testing.

I'm wondering if they would ever implement the engines into the airframe like the b2 for a military role?

One big difference with conventional design (tube with wings) is when you roll, people seated most outboard will get motion sickness, far more than
with the conventional tube design.

Also, far less people will have access to a window (ok, you will tell me that they can look outside thru a monitor screen, but it is not the same
thing).

Also, for a manufacturer point of view, it make it far more difficult to elaborate a strength version (adding two circular tube plug before and after
the wing, to keep the balance).

For all those reasons, industries (and the public probably) will be relunctant to adopt this.

I've never known anyone who gets motion sickness on a plane from there slow gradual turns.

The very large majority of people wont mind it one
bit.

It will have less windows...but hopefully the windows it will have are bigger, like the 787's, except even larger then them.

and by the time this thing comes to frutition moniters on the back of every seat will be the norm, so it would be nice if there were cameras on the
outside of the plane pointing in every direction, so the people in the middle can at least have something. Also, a more "dream-ish" type of layout
would have a "look-out" area near the front, where people can walk up to while in flight and look out an area with a LOT of BIG windows.

Actually, what I heard from an engineer on the project was that the people sitting further out, would have a higher angle in any turns, and the trays
would slide. I never heard anything about motion sickness. They were working on ways to make level turns to alleviate this issue though.

It would be cool to have hige ceiling windows...during night, not day, during the day you want to look down, not burn your retinas.

As for the side-2-side movement.
Just put a wall/divider in the middile of the aircraft.

as for meals and drinks and the ride comfort, it wont matter, since the airliner will do its sharpest turns on take offs & landings, at which point
you either will be done with you drink, or not have gotton one yet.
